Abstract

Strengthening critical thinking and collaboration skills has become an urgent need in 21st-century education; however, these skills remain relatively low among students. In fact, both are essential for navigating complex information, solving real-world problems, and working effectively in diverse teams. This study aims to examine the effectiveness of the service-learning model in enhancing the critical thinking and collaboration skills of tenth-grade students, as well as to investigate the correlation between these two skills in the context of a virus-related biology topic. A quasi-experimental design with a non-equivalent pretest-posttest control group was employed. The sample consisted of two classes (30 students each), selected using cluster sampling. Critical thinking skills were assessed through tests, while collaboration skills were measured using observation sheets. Data were analyzed using independent sample t-tests and Pearson correlation. The results showed that the service-learning model was effective in improving both critical thinking and collaboration skills, and there was a significant positive correlation between the two. The novelty of this study lies in the integration of the service-learning model into biology instruction on the topic of viruses, aiming to foster 21st-century skills through meaningful, experience-based learning approaches.

Abstract

Alpukat Deana memiliki potensi menjadi komoditas unggulan di Jawa Tengah. Ngesrepbalong sebagai salah satu wilayah di provinsi ini direncanakan sebagai sentra alpukat unggul tetapi masih terkendala oleh keterbatasan ketersediaan rootstock (batang bawah). Hal ini karena buah alpukat hanya memiliki satu biji. Kelompok Tani Alpukat “Gunung Berkah” di Desa Ngesrepbalong, Kecamatan Limbangan, Kendal telah merintis pembibitan dan top working alpukat Deana, tetapi skala produksinya masih terbatas dan rumah bibit kondisinya rusak. Tujuan kegiatan pengabdian ini adalah mempercepat kesiapan Ngesrepbalong sebagai sentra alpukat Deana melalui: (1) inovasi perbanyakan rootstock berbasis teknik pembelahan biji/embrio; dan (2) penguatan manajemen pembibitan, termasuk perbaikan rumah bibit dan pelatihan manajemen usaha bibit. Kegiatan dilaksanakan secara partisipatif melalui sosialisasi, pelatihan teknis, renovasi rumah bibit, pelatihan manajemen dan pemasaran, serta monitoring–evaluasi. Sekitar 90 biji sehat menghasilkan 360 potongan biji yang ditanam sebagai calon rootstock, sehingga ketersediaan batang bawah meningkat hingga empat kali lipat. Renovasi rumah bibit memperbaiki mikroklimat pembibitan dan kapasitas tampung bibit. Pelatihan teknis dan manajerial meningkatkan pemahaman petani tentang hubungan rootstock–entres, teknik pembelahan biji, perawatan bibit, pencatatan produksi, dan strategi pemasaran. Kegiatan ini memberikan landasan teknis dan kelembagaan bagi percepatan pengembangan Ngesrepbalong sebagai sentra alpukat Deana berbasis ekonomi hijau.
